SliceObject mounts one orthogonal slice (axial, sagittal or coronal) of an MriVolume on a screen-aligned quad and uploads the slice texture as R8 (grayscale) or RGBA8 (colour-mapped) to the GPU. The slice index can be scrolled at interactive rates; only the texture data is re-uploaded, the quad geometry is constant.

Used by the multimodal scene to mix MRI anatomy with the cortical surface and overlays in a single render pass: the slice is drawn first with depth-test enabled so cortical activity correctly occludes / is occluded by the slice plane.
